Worm gear ill is?! preferably disposed'et'; one endofshaft 2D;as'iridicatedin'Fi. 2. At the opposite end of shaftllfldsya co'uiiting dijskfn' disposed oppositea belt pulley zsnxdlymounted" on "astub' shaft" 29" ournaled in "the adjacent press frame i; and a belt 38 runs around the pulleys 2? and 28 thereby driving shaft 29 by and with shaft 20 and in the same direction.

Shaft 23 carries a pulley 3| (Fig. 2) fixedly mounted thereon and disposed opposite a pulley assembly 32 of well known construction, the same being preferably but not necessarily constructed in accordance with United States Letters Patents Nos. 2,186,477 and 2,151,189, said pulley assembly 32 being mounted upon the vertical leg 33a of a bell-crank lever 33 pivoted as at 34 in the adjacent press frame As shown the upper end of leg 33a of bell-crank lever 33 carries a horizontally disposed stub shaft 35 on which is mounted three belt cone members 32a, 32b, and 320. Cone members 32a and 320 however maintain on shaft 35 their transverse relationship from one to the other while the central cone member 32b is free to approach towards or recede from either of the cone members 32a or 320. The pulley formed by the cone members 32b and 320 is disposed opposite the pulley 3| on shaft 29, and a belt 36 runs around the said pulleys. The pulley formed by the cone members 32a and 32b is disposed opposite a pulley 3'l fixedly mounted upon a sleeve 38 forming a pulley shaft freely journaled upon the shaft 23, as shown in Fig. 2, and a belt runs around the said pulleys.

By the above construction of the pulley assembly 32, as cone member 32b approaches cone member 32c the pitch line diameter of the belt 36 between the cone members 321) and 320 increases, and simultaneously the belt pitch line of the belt 39 between the cone members 32a and 32b decreases. An increase in the belt pitch line diameter between the members 32b and 320 shortens the center distance B, Fig. 2. While cone member 32b approaches member 320, cone members 32a and 32b are separating so that belt pitch line diameter of the combination of 32a and 32?) becomes smaller, and hence at the same time the center distance B is being shortened the center distance C (Fig. 2) is becoming greater. Thus any increase or decrease of the center distance B is compensated for by a correlative decrease orincrease of the center distance C.

The separation and approach of the cone mem bers32a, 32b and 320 is governed by changing the position of the pulley assembly 32, to effect the shortening or lengthening of the center distance C and thecorresponding shortening or lengthening of the center distance B. The particular means shown for accomplishing the above change in center distances B and C is as follows: The outer end of the horizontal leg 33b of bell-crank lever 33 carries a swivel stud 40 having a thread bore to receive an adjusting screw 4| pivoted on the press frame through the instrumentality of a pivoting stud 4 a free to rotate about its center. On screw 4| is a locknut 42 which retains the screw in adjusted relationship to the bell-crank lever 33. By the above arrangement any adjustment of adjusting screw 4| will cause the variable pulley assembly'32 which is carried by the bellcrank lever 33 to swing in an are around pivot 34, and thereby change the center distances B and C.

Fixedly attached to sleeve or pulley shaft 38 are a number of delivery belt'pulleys 45 (Fig. 2) which carry the belts 46 which convey the printed papers from the press, said belts 45 also running over a drum 4! and being preferably provided with adjustable tensioning pulleys 48 and 49, indicated in Fig. 1.

If it is desired to increase the continuous speed 4 of the delivery belts 46 in uniform ranges, adjusting screw 4| is rotated to swing bell-crank lever 33 in a counterclockwise direction about its pivot 34. The variable pulley assembly 32 will also move uniformly in a direction toward shaft 23 causing the center distance B to become greater and the center distance C to simultaneously become uniformly smaller. As center distance B uniformly increases the effective pitch line diameter of the pulley formed by the combination 32b, 32c becomes uniformly smaller, while the effective pitch line diameter of the pulley formed by the combination 32a, 32b becomes uniformly greater, and hence the ratio of the drive from pulley 3| to the pulley combinations 32b, 32c, and the drive from pulley combination 32a and 32b to pulley 3'! has been uniformly changed, thereby speeding up the delivery belts 46, for continuous operation or movement. If it is desired to decrease the continuous speed of the delivery belts 48 in uniform ranges, the adjusting screw 4| is rotated to swing bell-crank lever 33 in a clockwise direction about its pivot 34.

The present types of deliveries have delivery pulleys rigidly attached to the shaft (such as 20) which receives its drive from an appropriate part of the folder, and consequently the delivery pulleys revolve at a definite speed with respect to the printing cylinders. In my construction the corresponding shaft 20 also revolves at a definite relative speed with respect to the printing cylinder which is desirable due to the fact that the counting disc 25 is mounted upon shaft 20 and thus rotates therewith at a predetermined ratio with respect to the printing cylinder. How ever, according to my invention when it is desired to increase or decrease the speed of the delivery belts 46 while the printing press is in operation, this may be effected without affecting the speed of the counting disc 26, by merely adjusting the screw 4|, thereby changing the position of the pulley assembly 32 and altering the center distances B and C and the belt pitch line diameters of the cone members 32a, 32b and members 321), 32c.

The construction shown discloses but one form of means for acquiring the, desired results, but it is understood that the type of drive from pulley 27 to pulley 28 can be any convenient arrangement such as a chain drive or gear drive;- also that the means for adjusting the pulley assembly 32 may be of any appropriate form to accommodate the particular shape of the machine to which arrangement is to be installed. I therefore do not limit myinvention to the exact form shown in the drawings, for obviously changes may be made therein within the scope of the claims.
